< p > 经 过 部 署 Kubernetes集 群 章 节 我 们 已 经 可 以 顺 利 的 部 署 一 个 集 群 用 于 开 发 和 测 试 ， 但 是 要 应 用 到 生 产 就 就 不 得 不 考 虑 master节 点 的 高 可 用 问 题 ， 因 为 现 在 我 们 的 master节 点 上 的 几 个 服 务 < code > kube-apiserver< / code > 、 < code > kube-scheduler< / code > 和 < code > kube-controller-manager< / code > 都 是 单 点 的 而 且 都 位 于 同 一 个 节 点 上 ， 一 旦 master节 点 宕 机 ， 虽 然 不 应 答 当 前 正 在 运 行 的 应 用 ， 将 导 致 kubernetes集 群 无 法 变 更 。 本 文 将 引 导 你 创 建 一 个 高 可 用 的 master节 点 。 < / p >
< p > 在 大 神 gzmzj的 ansible创 建 kubernetes集 群 神 作 中 有 讲 到 如 何 配 置 多 个 Master， 但 是 在 实 践 过 程 中 还 是 遇 到 不 少 坑 。 需 要 将 坑 填 上 才 能 工 作 。

< p > 按 照 神 作 的 描 述 ， 实 际 上 是 通 过 keepalived + haproxy实 现 的 ， 其 中 keepalived是 提 供 一 个 VIP， 通 过 VIP关 联 所 有 的 Master节 点 ； 然 后 haproxy提 供 端 口 转 发 功 能 。 由 于 VIP还 是 存 在 Master的 机 器 上 的 ， 默 认 配 置 API Server的 端 口 是 6443， 所 以 我 们 需 要 将 另 外 一 个 端 口 关 联 到 这 个 VIP上 ， 一 般 用 8443。 < / p >
